Fall Term

Winter Term

“Students are presented with a series of data points that they need to piece together using the different sensors that they have…. so it’s got a bit of a puzzle mystery aspect to it….they seem to have a lot of fun with it.” 

– John Getsoian, Laboratory Services Supervisor

Course Description:

Expect the unexpected! Radiation is invisible and everywhere: some is natural (radon gas) and some is artificial (nuclear power). Radiation can be useful (diagnosing and curing disease) and dangerous. You will learn how to approach technical problems that affect human safety by triangulating various data, designing unique approaches to radiation risks, and pivoting in the face of unexpected circumstances and results.

    • Fundamental concepts of radiation physics, health effects, protection principles, and detection
    • Collection and analysis of data in real-world contexts inside and outside the lab
    • Communication of research findings related to radiation health and ethics for technical and non-technical audiences

Term Project

Build a Geiger-Muller Counter, investigate radioactivity on North Campus, resolve three radioactive health risk problems in the field


Design and build detection equipment from the circuit-board to the case, learn and practice radiation detection and safety techniques, develop and practice methods for radiation detection
